Valga is a former Soviet air base in Estonia located in Jaanikese, northeast of Valga. It was listed on the 1974 Department of Defense Global Navigation Chart No. 3 as having jet facilities. It has mostly been plowed under into farmland. It is only from the Latvian border.
Long before the Soviet jet facilities were established here, the field was a known hub for Estonian civil glider and light aviation training (purilennukid) during the first independence period between 1937 and 1939.
